@fasterthanlime my primary issue with it is that the project clearly thinks this is a major headline feature because it's in paragraph two of the blurb, immediately after the description of what it is. which leads me to believe that their priorities do not align with mine.

Well, I'm curious now — macOS users, are you a "developer" and do you have Finder set to "show hidden files"?

@gsuberland@chaos.social avatar

@fasterthanlime I don't use macOS but "show me the hidden stuff" gets turned on at every opportunity. Windows Explorer? yep, hidden + system stuff shown. If I had the option to show Alternate Data Streams as files I'd turn it on. My TV? Developer mode enabled, all the hidden menu options turned on. If there's a checkbox that says "advanced", I'm clicking it. I want to be aware of all the things that exist.

You know the "one dimensional thinking" trope, where people run directly away from falling/rolling objects, rather than run a small distance to the side?

I just saw a letsplayer do that in a space game! With full 3D movement!

In deep space, they realize they've over-accelerated, and are heading towards a small satellite 13km away at 500m/s. They go "oh no, I'm going to crash into it again!" and slam on the retrorockets.
To slow down.

@foone this is where KSP has spoiled me, by making me pay attention to delta-V numbers. "I could alter my velocity relative to this object by 800m/s, or I could expend 20m/s of dV to alter my approach angle by 2 degrees for the same result".

@foone I went digging through the modding stuff and it looks like there is a resource management mod, but nothing to make the rocketry more realistic.

did stumble across this though, which looks cool: https://outerwildsmods.com/mods/trajectoryprediction/

Am I misremembering, or was there some cryptographic system where you could set up a container and have two keys to it, each of which provided a different file with no way for anyone to prove the other file/key existed?

ie, if the authorities forced you to decode it, you could give them the fake key and they'd only get the fake contents, and they couldn't prove that you have another key which reveals other contents?

Edit: it was truecrypt/veracrypt. Thanks!

@foone @whitequark I built a few crackmes that worked like this. similar idea to measured execution, except simpler and with much looser threat models.

@SwiftOnSecurity this is one of the reasons I prefer subs to dubs on anything I'm watching. everything has to be rewritten either way, often with changes to colloquial references for clarity, but with dubs they're also constrained by visual timing. they end up needing to choose between jarring sync issues or cutting details. (subs still do this, but to a lesser degree)

naturally understanding the original language is preferable but I've only got so many hours in a day.

@arstechnica I'll be honest, my bullshit detector is going off pretty loud. they're claiming that the malicious behaviour is in a "cryptically named function [... that] is not visible to security scans before or during installation of the app, or even with elaborate penetration testing" - then how did they find it? most of the claims read as if they've never seen an app permissions list before, looked at Temu's, and assumed malice because China Bad™

Idea: a USB-controlled gun, but the USB protocol implementation is the most cursed part.
Any ideas? I have a better one, but I'll start with that it's a USB printer class. Every time you tell it to print a page, it fires

I'd like to tell a quick story about successful troubleshooting.

A few months ago I rented a scissor lift to install lighting at my new office. When it arrived, the delivery person gave me a quick demo and off he went.

Well, when I went to actually use it - the lift went up by about a foot then stopped and screamed beeps of terror. It was broken!

But the display on the control read "18"

Rather than call the rental company, I searched "sinoboom fault code 18" to see what that meant.

gsuberland ,
@gsuberland@chaos.social avatar

@TechConnectify I had that happen at about 3ft off maximum extension, except the whole thing just stopped without error code. I assumed it had reached maximum extension and did the remainder of the gig lighting install by hand with a ladder, which was truly awful. Didn't find out until the last moment of teardown that the lift could go the full height.

It's funny how I've seen multiple people talking about how Microsoft Recall doesn't take pictures of DRM media, as if this was a conscious decision the Recall team made, and not just a natural consequence of how screenshots already work on modern windows.

gsuberland ,
@gsuberland@chaos.social avatar

@foone yeah it's literally just a case of "the DXGI stack can't see it because the image isn't decoded until it hits the hardware", and naturally they're using DXGI for the screenshot stuff because that's where everything gets composited.

My hobby? Disassembling and reassembling 3d printers.

Most people just call that "3D printing" but I want to be truthful to which part of the hobby I spend most of my time doing

gsuberland ,

@foone it's refreshing to see someone who uses 3D printers being honest about what using 3D printers is actually like.
